TEA CARTRIDGE.

Application filed September 26, 1923. Serial No. 664,881.

To all whom it may concern:

Be it known that I, BENJAMIN Hmson- HORN, a citizen of the United States, and resident of the city of New York, in the county of Bronx and State of New York,

have invented certain new and useful Improvements in Tea Cartridges, of which the following, is a specification.

The present invention relates to cartridges for percolating or extracting the flavor from tea-leaves or coffee. The invention pertains more particularly to that type of tea-cartridges, which is described in U. S. Letters Patent N 0. 1,310,? 96, granted to me on July 22, 1919.

In the Letters Patent mentioned, a-device for extracting essence from tea-leaves or codes is descmbed, comprising a bag of textile fabric which contains a quantity of tea- W leaves or cofiee just suficient for a single brewing. The mouth of the ha is drawn into folds and closed by a meta strip, ongaging and compressing said folds, thereby closing the mouth of sa d'bag, said strip attachin at the same time a suspending string to sai bag.

The main object of the resent invention is to provide a cartrid e t e bagcof which is in the form of a tu e, both ends of the tube being closed by a metal strip of the type above referred to.

With these and other objects in view, which will more full appear as the nature of the invention is etter, understood, the same consists in the combination, arrange- I ment and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the g pended claims, without departing from te spirit or sacrificing any of the advantages of the invention.

Two of the many ossible embodiments of the invention are illustrated in the accompanying drawings, in which Figure 1 is an elevation of a tea cartridge constructed in accordance with the resent invention; Fi 2 is an elevation of t e tube of which the bag is formed, having already attached to it a suspending string Fig. 3 is a section taken on line 3-3 01% Fig. 2

on a larger scale; and Fig. 4 is an elevation similar to the one shown in Fig. 2 ofthe drawings of a modification of the device, the bag being turned inside out in order to more clearly show the elements.

Referring now first to Figs. 1 to 3, in-

clusive, of the drawings, the numeral 10 in? dicates a tube of open mesh textile fabric, such as for instance cotton, it being made of a single piece of fabric that is folded along one of its longitudinal edges, denoted by the numeral 11, the meeting longitudinal edges 12 of the .two plies being joined by a row of stitches 13, which run parallel to the said meeting edges. A suspending string 14 is passed through one of the plies of the tube substantially at the transverse center line of the latter, its inner end being knotted as shown at 15, to prevent a disengagement of the said string from the tube. To the outer, that is to say the free end of the string is attached a handle 16 of pasteboard or like material, for a purpose hereinafter to be described. In preparing the cartridge, one of the ends of the tube is gathered into folds and a metal strip 17 applied thereto. This metal strip is shaped to assume the form of a ring, embracin the folded portion of the tube so as to hol the folds under compres-= sion. In this manner a bag is formed, tealeaves or codes for a single brewing being then placed into the same. The mouth of the bag is then closed by puckering the same and a plying thereto a metal strip 18, also shape to assume the form'of a ring, so as to lprevent escaping of the contents.

n brewing tea or codes with the 1mproved device, the cartrid e is taken hold of by its handle 16 and owered into the brewing receptacle, the free end of the string and handle being permitted to hang over the mouth of the receptacle, after which its cover is put in place. The cover thus holds the free end of the string and handle ready for further operation. llnto the receptacle is poured, either before or after the insertion of the cartrid e, a suitable quantity of boiling water. en sufficient essence has been extracted from the tea-leaves or cofiee within the cartridge, the cover of the brewing receptacle is removed and the bag withdrawn by graspmg its handle. i

The modification of the cartridge illus- Mid trated in Fig. 4: of the drawings difiers from the one above described in that the suspending string 1 is initially attached to the tube by the row of stitches 13. The string extends in this case from one of the transverse edges oi": the tube to its transverse center line and is then passed through the tube. In this instance, obviously one oi the metal strips serves also to securely hold the suspending string in place upon the cartridge. @therwise the construction and operation of the elements are the same as of those described in connection with Figs. i to 3, inclusive, of the drawings.

neeaeea Nhat I claim is A device for extracting essence from tealeaves or cofiee, comprising a tube of textile fabric having both ends drawn into folds, a metal strip encircling and compressing the folds on each end of said tube for closing said ends, and a suspending string attached to said tube passing through the same at a point intermediate its closed ends.

Signed at New York, in the county of New York and State of New York this 25th day of September A. D. 1923.
